- To all whom it may concern:

Be it known that I, HENRY J. ArrLn'roN, a citizen of the United States,residing at Detroit, county of l/Vayne, State of Michigan, have inventeda new and useful Improvement in Annunciators of which the following is aspecification.

This invention relates to a street car an nunciator for use on'streetcars to indicate the streets as the car passes along its trip. One ofthe advantages of the invention is to provide apparatus which ispositively tripped by devices placed along the route of the trolley.Suitable locking mechanism is provided to insure the non-movement of theindicating apparatus except when it responds to the desired action ofthe tripping mechanism. Suitable automatic reversing mechanism, ad-'ustable for different lengths of trips, is a further feature of theinvention. The details and the'nature of the broad improvements willmore easily appear when the detailed description of the apparatus isgiven.

In the drawings,

Fig. 2 is a top view of the 'annu'nciator case, part ofit broken away toshow the in; terior mechanismat the back of the case, taken on thesection line 22 of Fig. 3. i

Fig. 10 is aplan view of the reversing paratusfor the driving motor.

Fig. 11 is a side elevation of the. same. Theapparatus is contained in acase a and comprises an upper and lower storage roll n which winds asigncarrying belt are; by. the. teeth the sgirnchst wheels SpecificationpofLetters Patent. fatentgd luly 19 19, Application filed December 4, 1918.Serial No. 265,314 i f and g passing through the perforations h in theside'of the belt. These in turn are driven by the pinions attached tothem mesh ing with the driving gear which is'on the shaft 7r; (Fig. 2).This shaft 70 is driven by a chain m passing over the gear wheel Q n onthe shaft is and "the driving sprocket '0 on the main shaft. r

Now refer to Fig. 1. Thi s driving sprocket 0 is on theshaft p whichruns through the electro-ma'gnet'q' where it is provided with a slidingplunger r carrying the clutch part Sad-apte'dftO engage with thenormally continuously running clutch part't having the chain connectionu (Figs. 8 and 9) with the motor M. A pair ofbrackets' 'c at oppositeends of the several shafts already" described support not only theseshafts but some of the sprocket wheels and storage rolls, as will beobvious by inspection of the drawings. The storage rolls are driven byabelt to (Fig. 3) which runs over the sprocket wheels an attached to thestorage rollsb and cand over the driving sprocket 3] on the shaft '70.

The clutch is automatically shiftedf when the trip arm 2' has"been'thrown back, as shown in Fig. 5, by contactlwit'h the trip loops 1which'are suspended from theft'rol ley supporting cross wire? 2. Thetripswitch housing 3 is supported" to swing in the rectangular bracket 4: inthe following refer tofFig. Theglowe'r eiidof thebracket isbolt'ed tothe trolley pole 5. Atthe top of the trolley pole the flange and sleeve6 are bolted to the trolley pole" This sleeve supports one end of the'rockshaft Z, which is prevented from pulling out of the sleeve by" the pinand annular groove 8. The other end of the rock shaft is supported inthebearing 9 of the bracket 4 prevented fromlongitudinal movement by'the pin andgroove'lO. 'To this rock shaft i's pinned, to turn with it,by the pin '11, the hanger 12 that carries the switch box 3. Pinned tothe same rock shaft'is the end ofthe" arm 13 which carries a wheel "I4;that is forced. upj'aga'inst the trolleywire" '15 by the spring'16.'Obviously this trailing wheel arm and switch box is so mounted that thetrip switch b'okalways assumesfa"position ofparalleli'smwvith thetrolleywir eil5. nQtteammates tenses.

The trip 2 is made up of two pieces so that by the bolt and slot 17 thelength of the trip may be adjusted to thedesired position to strike theobstacle 1. The lower end of the trip arm has a slot and pin connectionat the end of the solenoid plunger 18, which carries'a bus bar 19adapted to en gage with the contacts 20. and 21.-

Now refer to Figs. 8 and 9. It will be found from these diagrammaticviews that the circuit from-these contacts leads around theelectro-magnet 9 that controls the clutch, the electro-ma-gnets 22, andthrough the battery B. The magnets 22 serve when energized to push upone end of the pivoted locking bar 23 'to release the wheel 2% on thedriving shaft p(see Figs. 1 and 3 where this is depicted). A post 25holds up the pivoted locking bar 23. Hencewhen the trip isoperatedsimultaneously the drive shaft 79 is connected with a source ofpower andthe locking wheel 24: is released to allow the revolution: of thedriving shaft.

Then it has rotated a quarter of a turn it carries the spider switch 26(which is loose upon the shaft 17) a quarter of a turn until the contactplate 27 bridges the terminals 28, and establishes the electric circuitconnected with the terminals, as .shown in Figs. 8 and 9. This connectswith the solenoid 29 in the switch boX 3 on the trolley pole. WVhen thesolenoid is energized it retracts and causes the trip arm 2 to go backto normal, as shown in Fig. 9. The locking wheel 24 drives the spiderthrough the adjustable clips 101 which are slidable along the rim (Fig.4). This allows the clips and driving 7 relationof the spider switch tobe adj ustable so that-if the signbelt gets. out of step with thedrivingmechanism, the relation of the switch and the driving shaft 70 can beallowed to bring the sign into step. 'The retarding spring 102 preventsthe spider running. ahead of the locking wheel 24.

t The motor is automatically reversed at determinable periods by meansof the mov able contacts 30 that are adjustable as shown in the dottedlines along the bracket 31. The contact 32 isin the form of a nut'slideable in the bracket 31 by the depending key engaging in the slot in thisbracket. The

other part of the nut runs on the screw 34:

1 that is drivenby the pulley and pulley cord 35 fro'm oneof the shafts36 on which the driving sprockets g are mounted. Referring to. Fig. 1,itwill be noted that one of these contacts 30 connects-with a wire A' A,the

-- other contact 30 connects with "awire B B,

and these in turn (see Fig. 10).conn'ect with the; solenoid sets 37 and3 8" respectively,

which have their plungers connected by the connecting bar 39 that at itscenter is "connected with the motor switch lever 40. Obviously when thescrew-causes the nut 32 to come 1n contact with the right contact 30right.

of Fig. 1 the circuit is established through B B around the solenoid 38,returning by the wire C C. This throws the lever to the The switch nutcontacting the left hand contact 30, energizes the solenoid 37 andthrows the switch 40 on to the left, reversing'the motor. Obviously-byad usting the contact 30 along the .slot 1n the bracket 31 the momentthat this reversal takes place can be adjustablyfixed.

Any appropriate means for compensatlng for the varyingperipheral'speedof the rolls in varying conditions of the winding of thebelt may be adopted. For instance, I have shown in Fig. 1 a familiar wayof doing this by utilizing a spring coiled around the roll shaft andfastened at one end of the shaft and at the other end to a pin in thewall of the roll.

In an 'annunciator, a belt carrying signs, drivingmechanism for said belt, a continuously running driving member, a clutchbetween the driving mechanism and the driving member, a trip switch forcontact with obstacles along theway, the said trip switchbeing of acharacter to remain tripped after having come in contact with one ofsaid obstacles, connections between the trip switch and the clutch formaintaining the clutch parts in engagement as long as the trip switchremains tripped, and a switch operatedby the belt driving'mechanism forelectro-magnetically returning the trip to its normal open position whenthe belt has been advanced the desired distance.
